About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-30
A double acting ISO 21287 compact cylinder, the ACEJ63X50-30 pairs a 63 mm bore with a 50 mm stroke that an external stop screw can trim anywhere in a 30 mm window, giving a usable extend range of 20-50 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. In practice, plan on roughly 935 N of real work at 0.5 MPa, which is about 95 kg of horizontal load.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarded cells. As a vertical-lift guide, the 0.5 MPa push equals roughly 158 kgf, so with a 2:1 margin it lifts about 79 kg vertically. A fixed TPU bumper at each end absorbs end-of-stroke shock, the hard-anodized aluminium body runs on an S45C hard-chrome 16 mm rod, and the 1/8" PT ports take standard air preparation. Note that no magnet is fitted on this version; order the optional -S code if you later need CMSE / DMSE switch position sensing.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-30 Is Used
Fixture clamping on CNC pallets
The 1558.6 N push at 0.5 MPa clamps machined aluminium housings on machining-centre pallets, while the 20-50 mm adjustable range matches varying fixture heights without re-plumbing.
Packaging line pusher arms
Mounted on an LB foot bracket, the short body fits under conveyor guard rails and pushes cartons up to about 95 kg of effective load at 0.5 MPa between the trimmed stroke limits.
Press-fit part ejection
Ejecting bushings from assembly dies, the cylinder lifts about 79 kg vertically with a 2:1 margin, and the TPU bumpers soften each eject cycle at 30-500 mm/s.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-30 the Right Cylinder?
At this force class the 63 mm bore delivers 1558.6 N push at 0.5 MPa; step down to a 50 mm bore (981.7 N) for lighter clamping or up to an 80 mm bore (2513.3 N) if the load grows. The -30 stop screw shortens the extend stroke only, never past the ordered 50 mm, and it is a mechanical end stop rather than a mid-stroke lock, so the piston still drifts if air is lost. FA flange and LB foot mountings bolt to the ISO 21287 face, and the female M10x1.5 rod thread accepts standard rod knuckles. If position feedback matters, specify the -S variant to enable the magnet for CMSE / DMSE switches.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-30 FAQ
This 63 mm bore model pushes 1558.6 N and pulls 1458.1 N at 0.5 MPa, and 2182.1 N / 2041.3 N at 0.7 MPa, with a theoretical maximum of 317.9 kgf at 1.0 MPa. It is double acting with a 50 mm stroke adjustable down to 20 mm via the -30 stop screw, runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with 1/8" PT ports and a female M10x1.5 rod thread.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA flange and LB foot options plus I/Y rod knuckles on the M10x1.5 thread. A fixed TPU bumper at each end absorbs end-of-stroke impact. Switch sensing requires the optional -S magnet code; this standard version has no magnet, so order ACEJ63X50-30S if you want CMSE / DMSE switches to detect position.
